Arcane Lock and keys

[Hawiboo]

Arcane Lock is cast on my front door. My door has a lock. The Disable Device DC on the lock is increased by the spell.

If I give someone else a key to my front door, can they open it?

I would presume having a key means you automatically pass the Disable Device check, but I don't think its stated anywhere.

Therefore, your key would not open the door.

But what an awesome prank to play on your neighbors or the local unpleasant governor.

Sneak in under the cover of night and arcane lock every entrance to his house.
